Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

I made a Twitter clone using Deno and Fresh
Did you check https://github.com/koskimas/kysely ? It was great when I used it. It has great TS support.

Type-safe S3 Select queries with Kysely
That’s where Kysely comes to the rescue: Kysely is a type-safe and devX-friendly typescript SQL query builder. It was designed to work with PostgreSQL and MySQL, but it exposes a few classes that can let us write queries without being connected to an actual relational database.
- Vue and trpc?

Announcing a new TypeScript ORM
prisma (mentioned in the article), zapatos, pgtyped and kysely are the most popular currently I think.
switch between a limited interface and a query builder (MikroORM, TypeORM). This feels like using two different libraries, switching between two different sets of limitations. Kysely is a nice query builder with good TS support, but MikroORM is using Knex instead so you're losing TS, and TypeORM has a custom query builder, less user-friendly than Knex.
-
Which ORM do you prefer with nodejs/Typescript project and why ?
I'd love to see Kysely as an option.
-
You might not need an ORM
Kysely[1] and zapatos[2] are excellent solutions for type-safe typescript query builders. It’s hard to go back to the days of spending 20-30% of your time in the object mapping layer.

Simple CQRS in NodeJS with Typescript
Querying the database (PostgreSQL) should not be ground breaking. Personally I like to have full type-safety so we can easily catch bugs during the development time without introducing any tests that are just testing the data type from our datastore to match the data type our API expects. I like to go database schema first, which means that we generate types from the database schema and work with those. Any change to the schema of the database is made with SQL migrations and after that, the typescript types are regenerated. Another approach is to use a code-first tool like TypeORM or Prisma. However in my experience such tools often produce not efficient SQL queries and are less easy to extend. In my projects I use library kysely (https://github.com/koskimas/kysely) with kysely-codegen (https://github.com/RobinBlomberg/kysely-codegen) to have a full type-safe SQL builder.

Type-Safe Printf() in TypeScript
There is an implementation of SQL that operates on a table shaped type, entirely at type level. For your amusement: https://github.com/codemix/ts-sql
There are a bunch of more practical takes that codegen types from your database and generate types for your queries, eg: https://github.com/adelsz/pgtyped
To me the second approach seems much more pragmatic because you don’t need to run a SQL parser in a fairly potato interpreter on every build
-
ORMs are nice but they are the wrong abstraction
ORMs suck, but raw SQL embedded in your code sucks too.
This might be good time to plug my TypeScript non-ORM: https://jawj.github.io/zapatos/.
I should say I also like what I've seen of https://kysely.dev/ and https://pgtyped.dev/.

An effective way to build a heavy CRUD Rest API?
Thank you for suggestions they helped me finding what I was looking for. I will either pick kysely or https://pgtyped.dev/, but first I will do some tests. Thanks!

compile-time SQL validations and type generation in TypeScript & Node
Cool. How does this compare to SafeQL, PgTyped, and Postgres language server ?

Petrol: embedding a type-safe SQL API in OCaml using GADTs
I would instead rely on code generation like https://github.com/adelsz/pgtyped, because the embedded type-safe SQL will never fully cover all the features of vanilla SQL, for example Common Table Expression (CTE), window functions etc.

There's pgtyped, which I believe does almost the same as sqlc

Kysely: TypeScript SQL Query Builder
For Postgres there is https://github.com/adelsz/pgtyped, sounds pretty much like what you describe?

Is postgresql-typed a good starting library for a production application?
Avoiding the cost of learning EDSL that many Haskell DB libraries provide, I found out that only postgresql-typed and postgresql-simple allow to write only raw SQL queries easily. As I extensively use pgtyped for production Node.js application, I am thinking about using postgresql-typed. While I could find many resources for postgresql-simple, the same cannot be said try for postgresql-typed.

This package is so underrated.
I would highly recommend trying out pgTyped if you want typesafe queries with postgres. It's fantastic!
